Abstract

Copper(I) and silver(I) complexes of formulae [Cu(NCCH3)4]+[A]- ([A]- = [B(C6F5)4]- (1), {B[C6H3(CF3)2]4} - (2), [(C6F5)3B-C3H3N 2-B(C6F5)3]- (3), and [Ag(NCCH3)4]+[B(C6F 5)4]- (4) are examined with particular emphasis on the strength of their M-N bond and its influence on the catalytic performance of these complexes in cyclopropanation and aziridination. To examine the strength of the M-N interactions, vibrational spectra of the related hydrogenated and deuterated species [Cu(NCCH3)4]+, [Cu(NCCD3)4]+, [Ag(NCCH3)4]+, and [Ag(NCCD3)4]+ are also determined. It is found that the metal-nitrile bond strength is an important factor for the catalytic activity of the respective complexes.
